Scirocco Central

What I mean is, if I floor it at say 2k rpm, anywhere between 2500 and 3500 reps the car won't accelerate anymore (the revs won't move or move very slowly) for anywhere between 0.5s - 2s and then go normally.

It happened to me twice 2 months ago, after restarting the engine everything was fine until today (didn't try to restart the engine).
It happens say once every 3-4-5 accelerations at that rev range.

Otherwise the car pulls normally, no ECU fault codes, no check engine light, my compression is perfect, didn't check for smoke but I doubt there is any.

Is there any chance is nothing mechanically wrong with the car (e.g piston, turbo etc) but some wire/sensor whatever is acting up?

Are there any usual suspects for the 1.4 TSI CAVD with this issue? Is it a common fault?

Could be misfiring; some older 1.4s misfire - a precursor to a much bigger problem I'm afraid.

A sensor may be restricting fuelling to the injectors. The engine management light wouldn't necessarily appear but if you take it to a dealers or have a mate with a device they ought to be able to see if there any fault codes...

It literally happened only like 2-3 months ago and the day I created the post, my mechanic said he can't really do anything since I have no fault codes and car runs fine when I bring it to him.

Also, the compression is perfect and as far as I can tell (might be wrong) car never missfired when warm, not even on cold starts during winter if using high quality fuel. I'm thinking is the wastegate or something but I'm putting this on hold until I can reproduce this issue consistently.

I was hoping it's a common fault or someone experienced that already and got to the end of it
